抖音作品代码在哪看
打开抖音抖音代码照片，在个人资料编辑页面就可以看见。
如果想更改代码抖音代码照片，步骤如下抖音代码照片：
1、首先打开抖音，进入页面找到编辑资料。
2、然后在个人资料编辑界面，选择抖音视频代码，删掉抖音视频代码。
3、最后输入想设置的抖音视频代码即可。
抖音上那些用字母数字拼出来的图片是怎么做出来的
抖音上那些用字母数字拼出来的图片的制作步骤如下：
1.打开浏览器，百度搜索【图片在线转换字符画】。
2.找到下图指向的链接，打开网页。
3.点击【选择图片】。
4.把要转换成代码的图片选中打开。
5.图片自动转换成功，点击【复制文字】，显示复制成功即可。这样就解决了抖音上那些用字母数字拼出来的图片的制作问题了。
