Hello,
I use [draw.io](https://www.draw.io/) to render technical diagrams. It is often of benefit to attach these to discussion topics to further a conversation or demonstrate an idea. [Draw.io](http://Draw.io) has the ability to export in [SVG](https://en.wikipedia.org/wiki/Scalable_Vector_Graphics) format, which is my preference when working with other discussion software.
When attempting to attach an SVG image generated through [draw.io](http://draw.io) to a Discourse topic, I am unable to do so. Instead, I receive this error:
> Sorry, but we couldn’t determine the size of the image. Maybe your image is corrupted?
I am currently uncertain if there is something special about the SVG format that [draw.io](http://draw.io) uses, or if Discourse is having trouble dealing with SVG files.
### Steps to reproduce
A sample SVG file is [available for your use](https://drive.google.com/file/d/0B3nYxBFHc-AZa1BGQzVaOF81a0E/view?usp=sharing). Alternatively, follow the steps below:
1. Head to [draw.io](http://draw.io) and start a new diagram.
2. Add any arbitrary shape (just one is fine) to the diagram.
3. Head to _File_ \> _Export As_ \> _SVG…_
4. Accept the defaults and hit _Export_.
5. Create a new Discourse topic.
6. Attempt to upload your SVG file.
**Expected Result** : SVG file is attached to the topic and (hopefully) rendered for users.
**Actual Result** : Unable to attach file. Error message received as follows:
> Sorry, but we couldn’t determine the size of the image. Maybe your image is corrupted?

Best #Contribute > Bug report I’ve seen in a while 👍
Turns out, [draw.io](http://draw.io) exports SVGs with a `` which isn’t supported by [the library](https://github.com/sdsykes/fastimage) we use to determine the image’s dimension.
Made a [PR](https://github.com/sdsykes/fastimage/pull/93) and pushed a [temp gem](https://rubygems.org/gems/discourse_fastimage) so we can use it 😉
