How can I determine the proper image size for my web page? I wanted to know before I download images from Dreamstime. Should I just download a medium size image and then resize it? Some of the sizes I would like are 1" X 1", 1.5" X 1.5", 1" X 2", 2" X 2". Is that the correct terminology for image sizing? Thanks for your help.
Depends on how much of the area it will take up. Smaller is better so loading time is cut down. But if you purchase a larger image and shrink it it will stay crisp. Web images are measured in pixel size, not inches. Here are some examples -
I tried to give a fast and easy answer HERE, but it's also true that if you download a medium or large size you have more options for cropping according to your needs. You have to decide in each case if you will use the photo "as is" or if you need to crop it. Cause if you want to crop it, or if you think you can use the same photo for another project in the future, a larger size is always better and gives you more flexibility.
Also keep in mind this verbiage from the RF license terms and conditions:
For Web use, you must not use the image at a width exceeding 800 pixels unless it is included in your site's design. If the image is part of a design and manipulated accordingly, the image width can be higher than 800 pixels.
