there are several lurking issues afoot with both posting images and actually being able to login at trad gang.
POSTING IMAGESphotobucket was the premier free online imaging archive that i happily endorsed well over ten years ago. it worked extremely well, very straight forward with direct copy 'n' paste and no muss or fuss. over time, photobucket decided to change their mission directive from offering a free image archival service to a semi-paying service, and eventually they wanted to enter into social media and compete with the likes of facebook to a fair degree.
as a result, what you have today with photobucket is nothing short of frustrating nonsense since their agenda is clearly all about social media and not about just offering us a quick and easy and free way to archive our images for posting at forums. photobucket is the PITS and a real PITA to get to the core of images so they can be easily posted AND accessed for copying. and their pages of popups and ads is SO annoying - particularly for when i need to grab a hunt image and make it into a "trad gang member of the week". i've come to really hate photobucket.
the clear answer for me was to drop photobucket like a steaming 'tater off the campfire grille and find a better free image archive service. enter
www.imgur.com - the best totally free imaging servce i've found to date and have been using for many years. i've got over 2800 images stored with them and without any social media nonsense attached. images are easy to copy 'n' paste, can be stored in albums, are easy to duplicate and replicate anywhere. imgur even has a private mode, for private image viewing, if need be.
FORUM ACCESS because they are not "real computers", there are known issues with mobile devices such as smartphones and ipads and tablets. mostly it's a browser problem. this is not just about trad gang, but other forums and websites as well. if you have issues accessing or logging into trad gang (or other forums and websites) with a mobile device, but no problem with a real computer, contact the mobile device manufacturer for assistance.
