Tips for Submitting Better Images

Read "How to Make a GIF or JPG image".

Before you submit a GIF or JPG image with your abstract, open it with your web browser. Look at it on screen. (The size you see there is what we'll call the "natural" size of the image. Then print the image from the browser and look at it on paper. Is it an image that you would be proud to see (at a reduced size) after your name in the Book of Abstracts? If the image does not look good to you on screen and on paper, then you should try to fix it before you send it to the ACS. Here are a few more tips for submitting better images:

  1. Submit a non-interlaced GIF or a very high quality JPEG file.
  2. Make sure that the image you submit is large enough. The smallest letter or number should be at least 10 pixels high, and preferably bigger.
  3. If you get an error message when you submit the image, telling you that the display size is too large to be accepted, do not immediately try to reduce the natural size of the image. Instead alter the display size. If you are using the "copy/paste text" method of submission, then enter a scale factor of less than 100% on the "copy/paste" submission form. If you are attempting to upload your abstract in HTML format, then open the HTML file with your editing software and shrink the size of the image; this will put instructions in the HTML file that force the image be displayed at less than its natural size.

When you view a shrunken image on screen, it might not be very legible. Very thin lines, for example, tend to disappear when an image is displayed at less than its natural size. Nonetheless, such an image might look quite alright when published. Why? Because the resolution of a computer screen is many times poorer than the resolution of print on paper. Thus, a line so thin that it becomes invisible on a computer screen can often be reproduced quite nicely on paper.

After you have submitted an abstract containing an image, check it online. If it is not very legible on screen, click on the image. This will present the image all by itself, at its natural size, allowing you to see what was previously invisible in the compressed image.

If you print your abstract after submission, and if you are using Netscape Navigator as your browser, you might find that a shrunken image does not print clearly. Try using another browser instead, such as Microsoft Internet explorer.

If you still have trouble creating a satisfactory image, tell us how you are trying to create it and we will try to provide additional advice or assistance.
