make sponsors logo more readable when logo is white in homepage

[outsideris]

In homepage, some sponsors's logo is white. So, people can't realize who is support us.
We should make them to people see the logo well like background color or shadow.

I'll ask OC about this.

It’s tricky. The simplest would be to contact the sponsor to upload the white logo with a background color, or a non-white logo that works well on white backgrounds.

Thanks @znarf. I asked (in Slack):

is that something OC could do for us? are logos unique to each OC, or unique to a company?

[outsideris]

There were some changes for background in OC. It looks ugly with our website.

@outsideris Sorry for the breaking change, we effectively shipped a major refactoring which is related to that.

I think you can avoid that behavior by switching from .jpg to .png while including these images. Before: https://opencollective.com/mochajs/backer/1/avatar.jpg After: https://opencollective.com/mochajs/backer/1/avatar.png

On our side, we'll check if there is a simple fix to have the background default to white when using the jpg format.

@znarf Thank you. We will fix them.

I fixed the black background issue. opencollective/opencollective-images#70 It's being deployed. Still doesn't hurt to migrate to png.

@znarf Thank you. It looks great.
