Greetings!
Thanks for buying the Flytabs template.
Did you specify a zoom image for all the products? As per the directions:
For the zoom function of the main photo, put a file in the “Add Image File” dialog (for the product) with a title of “Zoom”. With the
product open for editing, click “Add Image File” as shown below. Upload the file, set the file to unpublished, and be sure to not resize.
For best results, the Zoom image should be about twice the width and height of the full-size image.
I'm just guessing, but some people get confused between the filename and the file title. The filename can be anything like 'product.jpg.' But the File Title (separate field) has to be Zoom. The zoom image also must be unpublished. The system looks for an unpublished additional picture file that has a Title of Zoom. If it finds it, then it uses it. If it doesn't, then it doesn't use it.
Does that help?
Thanks,
Glen
