Log in to your Tumblr account and click the “Aa” button to create a new text post. Type or paste the text into the box and then place the insertion cursor at the point where you want to insert the image. Click the “Upload Image” button in the toolbox at the top of the text box to open the File Upload window. The Upload Image button has a camera with a small plus sign on it. Select the image you want to insert into the text box using the built-in file browser and then click “Open” to insert it. Click the “Post” button to post the text, along with the image, on your blog. Animated GIFs must be smaller than one megabyte and their width must not exceed 500 pixels. Tumblr does not support CMYK or other non-RGB color models.
