I am looking for the file to edit to change image upload sizes.
Currently it is set to 100X100 wich is too small for my preferences.
Any help is appreciated.

Please, post a link to your website i will have a look on that and will let you know if any solution exists for your demand. Chris, why don't you try the new Boss Cart version. You may check the demo site here. Actually on the main page the thumbnail size of the feautred products is 130px, and will enable to set a custom size in the forthcoming weeks. If you like the demo you may want to download it from the download section can be found among the navigatin links of this forum.

I am using 1.6 also tried to download the link from the above post
no luck says "you do not have permission to access this page".
So for now I took the store offline and am trying some other open cart software.
Thank you for the reply and hopefully i can download the above link to try the software I like the look of it.

The direct download link is sent via private message.
