Check out this video on inserting images into Prezi:
To insert an image into a prezi:
Select 'Insert' from the top menu, and then click on image.
If you want to select an image from your computer's hard drive, simply click 'Selectfiles...' from the pop-up menu that appears and browse to the location of the file you want to upload.
If you want to search the Internet for a picture, you can do it directly from Prezi without having to open a separate browser window or tab. Simply fill your search terms into the search bar that appears under 'Search images on the web'.
Click the blue 'g' icon to bring up further options.
We recommend selecting the check box that filters out all images that are not licensed for commercial use, especially for public presentations.
Once you have entered your search words into the search bar, click the search icon (magnifying glass) and the images available will appear in the sidebar
Scroll through the images until you find one you like. You can then either double-click it or drag and drop it onto your canvas.
After you have successfully added your image to the canvas, you can then use the Transformation Tool to size and rotate it as you wish (or delete the image if you want to).
Prezi currently supports JPG,PNG, GIF, and SWFformats.
The maximum size for any image is 2880 by 2880 pixels (unless it's inserted as a 3D background image). You may succeed in uploading a JPG larger than this, but this will likely cause various problems while editing and presenting. These limitations are set by the Flash platform and not Prezi. If you upload a JPG larger than these specifications, prezi will prompt you to resize the image. Click 'Resizeimage' to reduce the image to a usable size. For file formats other than JPG, you will need to use third party software to reduce the size of the image file.
"Progressive" or CMYK JPEGs and the JPEG2000 format are currently not supported.
You can upload multiple files from your hard drive at any time, simply select more than one file using the SHIFT or control keys when uploading.
Adding effects to images:
With Prezi, you can add effects to your images without having to download any additional software–allowing you to set a mood, cover up blemishes, remove redeye, and much more.
To add effects to a photo:
Click on the image you want to change while in Edit Mode and select 'Effects'.
This will bring up a new window. From here you'll be able to choose the effect you want to use.
NOTE: Public license holders will only see the first three effect options (Enhance, Effects, Frames). The full range of effects you see above is available only to Pro and EDU Pro license holders.
Once you choose an effect, you can choose to implement it by clicking 'Apply'. If you decide that you don't want to keep the new effect, click 'Cancel' at any time.
After you click 'Apply' you will see your image as it will now look. You can still cancel by clicking the X icon in the top-right corner of the window.
You can now choose to add another effect, or if you're happy, click 'Save' to return to editing your prezi.
Read more about the different image effects available here.
You can crop an image simply by clicking on it and selecting 'CropImage'.
This will bring up the image cropping tool. From here you can drag anyone of the four corners to crop your image. When you are happy click away from the image and you will see the changes take effect.
You can switch one image for another by clicking on it when in Edit Mode and then clicking 'Replace Image'. You will then be prompted to select an image from your computer to replace the existing image.
The second image will then occupy the exact same space as the orignal.
Note: It can take a few seconds for Prezi to start to import the second image. Please be patient.
Check out this video to see how you can replace and crop your images:
You can access even more options for positioning and editing your content (including layering objects) by right-clicking on any object in your prezi.
