Bigger Picture Please:
If you use Photoshop you can post fairly large pictures which are under 100k using the save for web function in Photoshop as described here:
Size, Quality and/or Format your Attached Images.. (Click here
If you want to post a larger resolution that is over 100K then you can host your image elsewhere and attach a link in the thread, but also please attach an under 100K version, (so the thread remains useful in the future, regardless of external links).
Other Hosts if you do not have your own site:
ImageVenue.com (3Meg max, free) pixentral.com (2Meg max, free) photobucket.com (1 Meg max free, 5 Meg PRO) mediafire.com (100 Meg per file, free)
Post a link in the thread to the site that is hosting the larger image.
You can also use these Free sites: (YouSendIt.com); (Podmailing.com);(Pando.com); (Sendspace.com) to send your original to your own email address, then open that email message, copy the link, and post that link in the thread.
Remember to attach a large
and under 100K version in the thread so the thread remains useful in the future, regardless of external links.
