That's a good question. I'm not sure what is the right answer. I'll do some research and get back to you if I bump into an decent answer. You should email the people at iPage as they probably can answer it..
I think the problem is in the function add_html_image_part. I'm printing out the $params array and I get this.
[content_type] => image/gif.
[encoding] => base64.
[disposition] => inline.
[dfilename] => uslogo.gif.
[cid] => 71798dca32a047c055770b02b2f45eac.
So it seems like it's working but.....
The image doesn't get inserted into the email and all I get is an attachment with this in it:.
Any ideas anyone?..
Cant you use <img> tags like tis.
Or embed tags?..
I've tried and it works for my email client (outlook express) but it doesn't work for my actual client who is using eudora. and he can view other images in other emails...
The only thing I can suggest is look at the script of other email that he can see pics in.
And use it with your own..
