On 6 November 2026 NiftyImages announced an Image Library. Agencies and email marketers can now upload logos, product shots and backgrounds once, organise them in folders with labels, and pick them while designing Personalized Images, timers, polls and other elements.
The library also lets you upload a new version of an asset and update selected designs, including images already sitting in sent emails. Agencies get a shared home for each client’s approved images, with existing Agency Access controls deciding who can see what.
This is a practical step for teams that manage multiple brands. Uploading the same logo from a desktop for every new design wastes time and risks using an outdated file. A central library reduces that friction.
What the Image Library actually does
According to NiftyImages’ What’s New page, the library supports JPEG, PNG, GIF, WebP and SVG files. You can create nested folders, add colour labels, and search by name, label, folder or file name. Stacking labels (for example “Approved” + “Logo”) narrows the results.
When you replace an image, you choose which designs should receive the new version. Slideshows, A/B splits and Rule Sets keep their own copies, so not every use is automatically overwritten. The update can affect images already delivered in emails.
NiftyImages notes that Agency Access still governs visibility, so client-specific assets stay partitioned.
These capabilities sit on top of NiftyImages’ existing open-based pricing and Personalized Images workflow that works with any ESP via image URLs and merge tags.
How email agencies already handle assets in open-time personalized images
Most email agencies running client programmes do not start from a blank canvas for every campaign. They maintain a small set of brand elements — primary logo, secondary logo, product photography, colour-correct backgrounds — and reuse them across sequences in Mailchimp, Klaviyo, ActiveCampaign or other platforms.
With open-time personalization the image is generated (or refreshed) when the recipient opens the email. That means the URL you place in the ESP can pull the latest approved logo or product shot at the moment of open, provided the template is set up to accept a dynamic image layer.
OKZest supports this through Dynamic Images. You design a template once with an image slot for the logo or product. At generation time (via the no-code editor, Zapier, API or MCP) you supply the URL or identifier of the correct client asset. Fallbacks ensure something sensible appears if the expected image is missing.
Teamwork features let multiple people — designers, account managers and, where appropriate, client users — work on the same projects and designs. Role-based access keeps one client’s assets and templates separate from another’s.
Because images are served on open rather than pre-rendered and stored in the ESP, updating the source asset and regenerating or letting the open-time URL resolve to the new version keeps already-sent campaigns current without a resend.
Comparing the two approaches for agencies
NiftyImages’ Image Library is a dedicated asset store inside the same tool that renders the personalized images. That proximity is convenient: you pick the library item while designing and can push version updates to existing designs.
OKZest treats assets as inputs to Dynamic Image layers. Agencies typically keep the master files in their existing DAM, Google Drive, Dropbox or brand portal, then reference the public or signed URL when creating the personalized image. The MCP and API let an AI assistant or automation look up the right design, inspect its parameters and return a ready-to-paste open-time URL without leaving the conversation.
Both models solve the “upload the logo again” problem. The difference is where the canonical asset lives and how updates propagate.
- If your agency already centralises brand assets in one place and wants the rendering tool to reference them, OKZest’s dynamic image slots + team access + open-time serving keep the workflow ESP-agnostic and pay-per-open.
- If you prefer the asset library, version history and update-to-sent-emails controls inside the same platform that generates the images, NiftyImages’ new library is built for that.
Pricing remains distinct. NiftyImages continues to charge by opens on tiered plans (Starter, Growth, Scale, Enterprise), with higher tiers unlocking more advanced features including the developer API and Store MCP.
Practical steps for email agencies today
- Inventory the assets you reuse across clients (logos in multiple formats, product hero images, seasonal backgrounds).
- Decide where the single source of truth should live — your existing DAM or inside the personalization tool.
- For open-time campaigns, design templates with dynamic image layers and clear fallbacks so a missing logo never breaks the visual.
- Use team roles so account managers can generate campaign-ready URLs for Mailchimp or Klaviyo without waiting for a designer, while designers retain control of the master templates.
- If you use AI assistants, connect via MCP so the assistant can discover the correct client template, confirm the image parameters and hand back the personalized URL.
Neither approach requires a developer for the day-to-day work of an account manager running multiple client programmes. Both keep the image URL model that works with any ESP.
Conclusion
NiftyImages’ 6 November 2026 Image Library makes asset reuse and version updates more convenient inside their platform, especially for agencies that want client-specific folders and the ability to refresh images already in sent emails.
Email agencies that prefer to keep master assets in their existing systems, generate open-time personalized images via no-code, Zapier, API or MCP, and pay only for images actually served can continue to do that with OKZest’s Dynamic Images, Teamwork and ESP-agnostic URLs.
The right choice depends on whether you want the library inside the renderer or flexible referencing of assets you already manage.
