Hi - can someone help me please?

For each row in my worksheet I need to be able to retrieve (from a URL) a
GIF image and save it to a folder on my hard-drive.
The URL strings includes some data from the corresponding row.

Any ideas or pointers please?

Searching this ng I found references to using chart.export and even
Stratos's low-level binary solution (from machine memory rather than a URL)
but are these really the best and only options?

Thanks

Believe Export and possibly Strato's solution are for saving a picture
originally located in an excel spreadsheet (or a picture of a range or
something like that). If you have a url in your worksheet that refers to a
gif file, then you probably want to use ftp to retrieve it and save it to a
local directory rather than open it in excel. A lot would depend on whether
you can access the file with ftp or not.

Thanks for the prompt response Tom,

Sadly I don't have ftp access to the website in question.
Could I force the image to be opened in an IE window and instruct IE to save
the file (i.e. via 'Save picture as...") programatically?

Thanks again
