Hi,
I suggest that you re-read the installation instructions and repeat the installation.
The .sql files are uploaded through your admin area in Zen cart.
Login to your admin, Tools > Install SQL patches. Upload the file and press go.
You need to make sure that IF you renamed your admin folder.(As suggested in the security patch you applied on Zen Cart) That you also did this to you Ajax Image swapper folder mod where your folder name is admin.
You need to ensure that you name ALL folders in the AIS MOD called your_template are named that of 'your' template name.
Connect to your site via FTP and go to admin/includes/template
if there is a folder called some thing like Glacial Age (your live and working template) you must name the your_template folder in the AIS Mod to the exact folder name you have for the Glacial Age folder.
Normally, there is a few other folders in there also like classic, template_custom, template deafult. Leave these. the Glacial Age (or however it is named) folder loads first.
It shouldn't matter at all which template your using in regards to ajax image swapper working.
Re Upload the AIS via a good FTP program like filezilla (it's free).
To see if it is working.. you should have 2 menu options in your admin section.
Login to zen cart admin. Check : Configuration > Ajax Image Swapper
AND
Catalog > Ajax Image Swapper Manager.
If any menu missing it is not installed correctly.
Fuel Slimbox I would suggest to leave on while testing. When working then disable.
