While it is possible to add images using IH2 (in the IH manager - admin >>> tools >>> Image Handler) these will always be considered as ADDITTIONAL images if a main product image already exists. IH2 will append _01 . _02 (etc) to these as you upload them.

This feature also looks at the current location of the current main image. If you have (earlier) placed the product's main image in a sub-folder in the images folder, it will load all subsequent additional images to that folder.

However, by default, if there is NO main image for a product, it will load what it calls the "default" image into the main image folder.

This sounds a bit Catch-22 -ish I know, but essentially IH2 is NOT used to upload or locate the default image. It can be used as a quick tool to upload ADDITIONAL images - but even these are best loaded via FTP.

You may by all means create sub-folders in the images folder (that can match by name, your categories) - as long as you understand that folders should all be lowercase letters with no spaces or strange characters.

If you have a category called Gold & Silver, you cannot have a folder called Gold & Silver... It will have to be something like gold_silver

Anyway... IH2 will automatically locate the folder where the image is stored AS LONG AS the database reference is correct.

So... if you decide to store an image in folder gold_silver for a particular bracelet, the database must have the following in the images field:

gold_silver/bracelet.jpg

IH2 also uses that reference in its workings, so if you later want to add an additional image via IH manager, then all you do is call upo that product and using the browse/upload feature, put the additional image into play. IH2 will appropriately re-name that image so it is consistent with the additional images formula used by zencart.

Don't use IH for uploading main images. This should be done via FTP.

If you decide to put your images into sub-folders, it is vital that the DATABASE reference is corrected.

Easy Populate is best used for making this kind of change - not IH2.
