ASPImage on the fly

[Mohamed Hosam]

I want to use ASPImage to resize photos and show them to user as thumbnails
on the fly (I do not want to save them). Any idea how to achieve this?

On their page, they advise me to use Response.BinaryWrite, so this is what I
did:

Response.ContentType = "Image/Jpeg"
Response.BinaryWrite Image.FileName

Instead of showing the image, it shows the binary contents!! Any help is
appreciated.

Very good - I'm glad it worked!

Only drawback with the dynamic resize is scaleability - repeatedly resizing
the same images over and over again for every page load. However, you should
find that the images get cached in the local browser which should cut out
some of the repeated resizing.
It may be a more scaleable solution to do the resizing when an image is
uploaded and maintain two directoruies (one for full size and one for
thumbnails).
Still, not taking any credit away from what you've done - it obviously works
and it's probably tought you a little bit about some of the more interesting
aspects of using ASP pages as 'information generators' (eg. you can do the
same with an ASP page that generates XML on the fly).
