Re: Adding pictures?

It's a known problem & occurs when initially getting jpeg fileinfo before imagemagick or GD is used.

The programmer did fix it.

Re: Adding pictures?

Followup on Eddy's problem files. Eddy's file#1's EXIF data says the image dimensions are 5504x3096 even though it had already been resized to 800x450. phpbb's fast-image-size tries to get the image size from EXIF first and, if it can't, then tries to get it from the SOF0 marker. So that must be wha...

I found Geo Orbital, https:// www. geoo.com . This would be an easy aftermarket install for us to modify new bikes before shipping to customers.

Re: Need a battery builder for LiFePO4 ATV

The electriccarpartscompany webpage lists the battery type SE130Ah standard busbar P/N as "SE130AH 57 ". Could that "57" denote the dimension you want and does that mean they have or can get it (it also says, "The last two numbers are the center post to center post distance (mm). For example: CA35V4...

If I needed a laptop battery I'd look for one at Amazon because: 1. Lots of choices there. 2. They have reviews. The quality of their reviews is sure not as good as in the past but they have them at least. 3. You can buy a battery that's "Sold by <some seller> Fulfilled by Amazon ." Then, if somethi...

Re: iMortor / UrbanX External Battery

There might not be a ready-made XT30 cable in the length you want. Looks like most XT30 charge cables are 12" long. So get one of these, some wire, & make a cable in the length you want. https://www.amazon.com/Female-Connector-150mm-Silicone-Battery/dp/B073WWWMQP https://www.amazon.com/pairs-Female-...
