I will probably need to update those instructions, they may be a little dated.
Im on my mobile right now, just went to
http://tinypic.com and pressed upload, browsed my phones pictures, chose a pic to upload, clicked Upload and typed in a captcha code.
Then it offers several styles of link you can copy including the one used here with [IMG] tags
Im going to paste it now:

Size may be an issue if your phone takes huge photos, or they may post sideways if posting from an iphone.
Anyone else have a slick ways to upload photos while surfing lp101 from a phone?
