* Like [https://en.wikipedia.org Wikipedia] is a popular text OER repository, [[commons:Main_Page|Wikimedia commons]] is an image OER repository. You can search for your topic in Wikimedia Commons, by simply typing the topic name in the search bar. We will do this for ‘Digital Story Telling’ (DST) which is the OER being created as an exemplar in this toolkit.

* To get images that are OER, you can provide OER as a criteria in your search itself. In Google image search select <u>Settings → Advanced Search</u>. In Advanced Search, you can select Usage Rights as ‘free to use, share or modify, even commercially’ to get OER that you can re-use, with or without modification.

You should also create a drawing on an issue connected to your topic. One possibility is you could use any image you found as a reference, and draw it using Tux Paint. The left tool bar also has an eraser in case you want to erase any part of your drawing!

We have created two drawings of a tree, one without fruits (shown in previous section) and one with (below). The second one is created simply by painting small fruits on the earlier painting and saving the same. Playing these two images recurrently in Tux Paint creates a simple animation of the changes in the tree over the seasons.

You have an option of capturing the entire display on your screen or selecting a smaller area. For the latter option, chose ‘select area to grab’, as shown in the image. Then use your mouse to drag drop the (rectangular) area you want to capture. (Move your cursor to the left top of the area, keep your left mouse click pressed, move the cursor to the right bottom point and release it).

You can thus easily create an image OER using Screenshot of an image from your computer or the web. As mentioned earlier, taking a photo of a copyrighted material (such as a photo), is a violation of the copyright law, with exception given for ‘fair use’.

GIMP will open a form asking for reduction in quality. You can reduce quality up to 30% without visible degradation in quality. We reduced the size of a file from 10.7MB to 1.2 MB using above approach.

We have inserted the image of the students interacting with the Community Health Institution official and a text box by the side of the image. The combination of an image and text resource adds more power and meaning of the information conveyed, than only the text or the image would have conveyed.
