is there any way to manipulate images in vb.net in asp.net?
i have a 280x280pixel jpg file, and want to display it in 2 sizes, 280x280
and 70x70... without having to create 2 files... (actually there are some
100s files, dont want to duplicate them...)
any way to use an image class or something to resample the image and get the
stream as a jpg file displayed on an aspx file?
i know there were com components for ASP to do this, like ASPImage, but
cannot install custom components on my server.

You probably want something like this:

Use the single thumbnail browser and adapt to code to take in parameters for
the sizes you want.

I used something similar for a photo gallery site, it works fine and the
images look really good :)

But be careful with .bmp and .png files, they can have problems displaying
on a page.

See http://aspalliance.com/chrisg/default.asp?article=152 for more info.

On a side note I was initially using an image component, but stopped as the
company never replied to our emails about the product, so a bit of searching
around saved us $500 for a component by doing the coding ourselves :)
 
You can do anything with ASP.Net that you can do with any other programming
technology. To manipulate images, use the System.Drawing namespace.
