Filters, effects, and stickers let you add that extra special touch to any photo. Pixlr allows you to edit and print your photos in no time. You can make your pictures more beautiful with these simple tools. (This was originally posted on our college circles of innovation blog.Pixlr puts you in the driver’s seat and gives you complete control. Try an image editor like Pixlr to resize your images to be smaller in file size (go to Image -> Image size to resize). You might try to keep your individual images under 100kb and the total size of all images on your page under 1 megabyte. I would recommend not using very large images in your Canvas pages, and not too many images. How can I lower the chance of this issue happening in my courses? It adds a button in the toolbar that will clear your cache any time you press the button (and optionally it will reload the page for you, too). See this Clear browsing data page for more details.Īnother option is to install the Clear Chrome browser extension for Chrome. Reload the Canvas page to see if that fixes the issue. You can also get there directly by going to this URL: chrome://settings/clearBrowserDataĬlear recent images and files from your browser like so: Click the 3 vertical dots on the top right of Chrome, go to Settings, and scroll to the bottom and click on Advanced. In Chrome, you can clear all the images and files stored by your browser. Hit control-shift-i again to close the developer tools pane. Then right-click (or control-click on macs) on the reload button and select Empty Cache and Hard Reload, as pictured below. In chrome, you can hit control-shift-i (or command-shift-i on macs) to open the developer console pane on the right. Sometimes it is necessary to empty that cache first to force all images or other files to be downloaded again. That usually fixes the issue for me, but if things are still not working and you don't think it is poor network connectivity, there are some "stronger" options below that you can try. Control-shift-R should tell the browser to re-download everything. Your browser keeps a cache (store) of images and files it has downloaded before. If a simple reload of the page does not appear to be fixing the issue (control-R or command-R on macs), try control-shift-R (or command-shift-R on macs) to reload the page and force everything to re-download. If none of those are issues in your case, try one or more of the options below, starting with the first: Run the link validator in Canvas to check for and fix broken images and links. The pasted images are still being loaded (or not loaded) from a different course that you may not have access to. Copying and pasting images from one course to another does not work. If images are not showing up in one course but they show up fine in others, it may be because you (or the course builder) copied and pasted images into the course rather than uploading images into the course. You can also check the status of Canvas servers, but that is rarely the issue. Run a speed test to see how fast your Internet connection is. If you are trying to connect over a poor wifi or cellular signal, that may also cause the issue. Make sure also you have a decent Internet connection. Try the Chrome, Firefox, or Safari browser instead. Canvas will not work correctly with Internet Explorer, for example. For more discussion of this issue, see these threads on the Canvas community site: Disappearing Graphics and Why are my jpeg images disappearing.įirst, make sure you are not using an old computer with insufficient memory/RAM or an out of date operating system or browser. This puts a brief but potentially heavy load on your computer, your home or school network, and the Canvas servers. When you load a page from a web server like Canvas, your web browser may actually be making dozens of requests from the server - one for each image and CSS and javascript file used on the web page. There are various reasons why this may happen - your school or home network may be clogged or having other issues, Canvas servers are overloaded, your computer is overloaded, etc. In my experience (been using Canvas since 2011), this is just a temporary issue and reloading the page fixes it, and usually the cause is my school network, not the Canvas servers or my computer or browser. Occasionally you may notice that one or more images do not appear to be loading on a page in Canvas - especially pages that have a lot of images. Feel free to add your own suggestions, corrections, etc. In response to the Disappearing Graphics and related posts here, as well as related questions from my own faculty, here are some tips for what you might try doing if you run into a situation in which some or all of the images do not appear to load in Canvas.
