Picture displays on Web Apps

While running the Erewhon Web Demo from Jade (and any other web app that I have) I find that the images appear with no colour and are blurred. I've tried deleting all the .jpegs in the Bin directory but that didn't help either.
Any Ideas?

Rgds,

Since you have the application running, presumeably you've run the "initializeData" JADE script, which loads the data and pictues into the database. The Web application then fetches the images directly from the database when serving the web pages, so removing them from disk won't make any difference.

However, your problem sounds more like a resolution issue. In the "Settings" tab of your workstation's (Control Panel) "Display Properties", how many colours do you have set for your "Color Palette" ? You should probably have at least 256 colours set... does your workstation's video card handle this many colours ?

Failing this, you mention that you experience this problem with any web app, which suggests your problem may be related to your web server or browser client. What flavour web browser are you using ? What version of IIS are you using ?

I've had the same problem, and as Darrell suggests, it IS a resolution issue on the PC running the Web application. I seem to remember 256 wasn't high enough.....some trial and error should solve it.

Darrell/Graeme,

Thanks a lot for your help. It was a resolution issue and the images displayed fine after I changed the colour palette on the workstation running the web app to more than 256 colours. Initially I tried changing the resolution/colour setting on my workstation (different from the previous one) but that of course didn't help.

For Info purposes, I was running IE 5 on my workstation, and IIS 3.0 (version 4.0 SP-4) on the NT workstation running the web app.
