How to make your pics "hover to zoom"??

[pezmanscardvault]

When I look at my own auctions, my pics do not seem to have the "hover to zoom" feature. Do you need to use gallery plus to have that feature or is there something else to do when listing??

Borrowed from shipscript :

Zoom and supersize depend on the size of the original photo you upload to eBay.

If the longest side of your photo is:

under 500 pixels, eBay will reject the photo. A larger photo can be made too small if you crop with eBay's editor.

under 640 pixels (500-639), neither supersize popup nor mouseover zoom is available. The static photo may be displayed as small as 300 pixels.

under 800 pixels (640-799), a supersize popup will be available, but there will be no mouseover zoom.

up to 1600 pixels (800-1600), both supersize and zoom will be available.

over 1600 pixels, eBay will shrink the master image to 1600 pixels and the above will apply.
