I dunno about firefox but IE has a setting in it to resize graphics to fit the browser window, or if not checked to leave them alone = graphics off to the right if bigger than your window is open.

Look under internet setting options advanced in control panel.

Also - Some of the photo storage web sites will have settings to recognize graphic to fit user browser window and they will size graphics to fit.

When you open the photo on your computer at home you are probably looking at it in windows picture and fax viewer which resizes it to fit your screen. When you look at it on an internet site your browser opens it and does not automatically resize it unless you do as Mikie says, which most people will not know to do.
My suggestion is to resize your photos before uploading them to tinypic. It is very easy to do using Irfanview which is a free program. Here is a link to a tutorial which explains how to do it in simple terms and has a link to the irfanview home page where you can download the program. Few people have their monitor resolution set at 640 x 480 any longer so it is safe to make the width of your pictures that you want to post 800 pixels, but I wouldn't make them wider than that.
By the way, to answer your question asked in another forum, no - you cannot remove the pictures once you posted them.
One more suggestion. Have you thought of using photobucket to upload your pictures you want to post instead of tinypic? They are run by the same people and work very much alike. Just go to photobucket.com and open a free account. Your pictures stay in your album on photobucket so that you can see and post them again later if you want to. Another advantage is if you make a mistake and post a picture you would like to remove you can delete it (or change the name) in your photobucket album and people will see a red x where the picture had been.

Hello...

Thanks for trying to help me out. I actually had someone tell me I could get the photo removed by tinypic and I decided to try. Sure enough, I used their contact email form on their site and they responded right away. They asked for the address of the photo which was under properties and within about 15 minutes it was off of the thread. Just thought someone in the same boat might like to know that at some point.

Bob...when I said I was viewing it and it was not too large and the text was not scrolling, I meant I was going to the thread on my firefox browser and looking at it. I still am not understanding why so many other people on the thread were trying to look at it and were seeing a very large photo and it had effected the text to the point that they had a scroll bar at the bottom of the page and had to scroll to the right to read the text. But rest assured, that I didn't intend to post that large of a photo. The tinypic site never used to offer a choice of sizes that I noticed and now they do and it was set at default, which was too large. So from now on, I will make sure it is set at a smaller size.

Someone on the thread suggested, maybe I didn't put enough space between the two photos and it was attempting to put the two photos side by side and that is why the text had to be scrolled. Which still doesn't explain why I didn't have to. I still wonder if it is my screen resolution. At this point, the problem is solved, I guess I am just curious. :-)

I checked the options for the Firefox browser and I don't see a checkbox that you describe that automatically resizes graphics on the browser page. But, I am getting a new computer soon and hopefully I will have fewer browser problems after that.

Yes, I am aware of photobucket and just haven't wanted to store my photos online. I may at some point but can't right now. Thanks for the free Irfanview program link. Looks very useful!

Thanks... adam :-)
