When Photobucket went ten toes up on me I got that Imasomething or other. Works pretty good and it's up load picture's at the size you want. Mine are always 600 pic's on the long side!I was once really dumb about using a computer posting pictures I wanted to share. I had all I could do to get the computer on the internet let alone share pictures. A kindly old fellow in AZ. took pity on me and got me going in the right direction on the easy way to post pictures.
Resizing pictures is a challenge for many of us and was for me for sure. He suggested I go to a photo storage sharing site and provided a link, was sonyimagestation.com No longer there but they setup a process so our pictures went to shutterfly.
Shutter fly how ever isn't a site who's 3d party sharing works on all forums. A new one had to be found many went to Photo bucket and that worked great till recently.
Now many I know are checking out other sites and have found several that will size the picture for you and allow easy sharing on this site and others too.
Picturetrail.org works and is easy to upload pictures to. Draw back is limited storage of pictures.
postimage.org is also a good site and seems space in not limited.
My favorite raised bed watering system.
imgurpictures is also a pretty good site I am finding which is new and I am still playing with.
All these site size the picture for you and allow you to post them on many forums. If you do not have 25 post or been a member for 10 days you have to use a 3d party picture hosting site like above to post pictures here.
