I'm still a newbie and struggling to figure this out.
Click on Blues LG (Loupe Style), AMD (Manufacturer), Clarion (Model). Hit Search and you will see a picture of glasses.
Should show a compatible product for all selected items. Now, choose Indie LG (Loupe Style). The image disappears. This doesn't happen on my local computer. The app runs fine and shows every picture.
The images are stored in www folder. See the codes. This was writen by the previous programmer and he had the app running fine with the same pictures. So I don't know what has changed since then? The only thing I have changed is one picture (Zolar) and that picture did show up. Any help would be greatly appreciated!!!
please excuse the code mess because I thought the solution was combining the server.r and ui.r into app.r and apparently, it didn't.
