the images are there weather it is finding them is another question i would need to put in some echo "file found" along the way to see that. but if you can not see a problem with that code then they must be getting found just not getting displayed.

as the images will be sent out in a email the absolute path to them must be used when displaying them. for the file exist part could the image file along with the extension be found using relative paths. would this section work if the relative paths where used.

when it comes to display the image then the absolute path would have be used to displayed the image as it is being sent out in an email.

the file extensions can only ever be gif, jpeg or png files, it there another way you know of i could get the image to display in the email.

i can upload the page which is to be sent out if that would make this problem clearer for you.
