Making images for upload

Getting images from other applications

Most of the images you'll want to attach to eCAT you'll already have as an image. These you can just upload as described in the Importing Images section.

But sometimes you'll want an image of something you can see on your screen, but which isn't actually an image. A common of example of this is a chart shown in Excel or OpenOffice. It looks like an image, but you can't export it from Excel as an image. What to do?

There are a variety of things you can do to turn something you see on the screen into an image for upload to eCAT:

An image on a web page

Right-click on the image (Ctrl-click on Mac), and select "Save image as".

An image in another application that can export images

Lots of applications that deal with images of one form or another can export them as a standard format such as PNG, JPG or TIFF. Once exported, the image can then be uploaded to eCAT. TIFF is often preferable for scientific images as it can include metadata.


Excel does not allow export of charts as images. However, you can add a capability to your copy of Excel which will allow you to export a chart as an image. This is fully described on this web page.

OpenOffice Calc does not allow export of charts as images. However, you can copy the chart and paste it into OpenOffice Draw, which does allow export as an image. Select the chart so it has green handles, copy and paste into Draw, then in Draw while still selected do File | Export.

An arbitrary area of your screen

Sometimes you'd like an image of part of your screen - for example a portion of an image, or a portion of a web page. Different operating systems provide different functionality and applications for this - here are some options:
