update image problem

[Anon]

hi,
I stored image as binary into the database. When i tried to update the image, the brower didn't load the new image unless i pressed Refresh button of the tool bar.
Can someone help me to force the image to expire from the brower cache by using PHP code or whatever?

Thanks in advance
Angela

this is a browser problem. depending on how you are calling it, you can generate a random number to attach onto the source image name. example: ".....image.jpg?84345".

give it a shot, it works for some situations, but not for others. BLOB objects have to be dealt with differently. instead of storing the actual image in the database, i just store the file name. i've had better luck and less troubles this way (but you tend to get a mess of files if you don't keep it clean)

blah blah...
