The files in this directory CompMethods/docs/ include images and all the files necessary for rendering the Jupyter Book documentation. One image CompMethodsLogo_gitfig.png is only used for the GitHub social preview image. GitHub suggests that this image should be 1280x640px for best display. The image we created CompMethodsLogo_horizontal.png is natively 759x267px. We do the following to resize the image.

1. Open the image in Adobe Photoshop: File > Open
2. Open the Image Size dialogue:
3. Adjust the canvas size: Image > Canvas Size. Because the 759x276px image is relatively wider than the optimal 1280x640px GitHub size, we first adjust the canvas size. We have to add a little width and some moderate height. So here adjust the canvas width to 760px and then increase the height to half that size 380px.
4. Adjust the image size: Image > Image Size. Now adjust the image size to the GitHub optimal 1280x640px. The dimesions will be correct and nothing will be stretched.
5. Save the image as CompMethodsLogo_gitfig.png.
6. Upload the image CompMethodsLogo_gitfig.png as the GitHub social preview image by clicking on the Settings button in the upper-right of the main page of the repository and uploading the formatted image CompMethodsLogo_gitfig.png in the Social preview section.
